Title: Battery
Inventor: HARADA MASATO
IPC: H01M50/167
Filed: 1982-03-26
Abstract: PURPOSE:To smooth the fitting of a battery into an appliance without deteriorating the resistance of the battery to liquid leakage and changing the total height of the battery, by restricting the level of the top of exposed part of an insulating ring within an appropriate range on the basis of the top of the open end of a case. CONSTITUTION:The level of the top of an insulating ring 4 is set at the top of an anode case or set lower than the top. If the level of the top of the ring were set too low, the top of the anode case might come into contact with a cathode plate after the anode case is calked. For that reason, the height difference between the top of the anode case and that of the insulating ring located below the former must be not more than the thickness of the case. If the top of the ring is located above that of the case calked, the height difference must be  equal to or less than 20% of the case thickness to enable secure fitting into an  appliance. The upper limit to the height of the top 4a of the ring 4 from that of  the open end 2a of the case is 20% of the case thickness (t) and the lower limit  is -100% of the thickness.

Title: Optical waveguide type device
Inventor: HATTORI TETSUYA
IPC: G02F1/05
Filed: 1991-03-14
Abstract: PURPOSE:To offer the optical waveguide device which operates without depending upon a polarized wave direction and requires no complicate potential adjustment, etc. CONSTITUTION:An optical waveguide 24b which propagates light in the direction of the optical axis is formed on the surface of a substrate 22 of uniaxial ferroelectric crystal. Electric fields 26a and 26b apply an electric field in the optical axis direction of this optical waveguide 24b. Consequently, the refractive index to the light traveling in the optical waveguide 25b in the optical axis direction varies almost uniformly as to an optional polarized wave perpendicular to the traveling direction. The refractive index at an optional position in the optical waveguide 24b can easily be varied. In this case, the variation in the refractive index does not depend upon the polarization direction of the light traveling in the optical waveguide, so the device having no polarized wave dependency can be offered.

Filed: 1978-04-28
Abstract: PURPOSE: To prevent contamination due to the movements of ion impurities from a seal portion into a liquid crystal bulk by using a sealing agent, to which an ion exchange resin is added, thereby to produce a liquid crystal display device.  
     CONSTITUTION: An anion exchange resin, which has been subjected to treatments with acid, alkali and organic solvent, and a cation exchange resin are mixed in an equal quantity to make the granularity uniform. After that, a seal agent of expoxy is added in a quantity of 0.01 to 0.1 %. This is used to seal the upper and lower substrates. By the use of the seal agent thus far described, the moisture stealing from the outside after having passed through the seal portion is trapped by the ion exchange resin contained in the seal portion so that it can be prevented from reaching the inside of a display device. On the other hand, the ion exchange resin in the seal agent has the result of gap formation in place of the conventional glass fibers.
